In 1969 a rock concert was held in witch-haunted Arkham, Massachusetts. The crowd
was treated to performances by stars of the local "scene' such as The Plasma Miasma
and The Gyre Falcons. Police believe that psychedelic drugs were consumed. As the
drugs and music peaked, Miskatonic University's celebrated Philosophy Professor,
Stephen Firth, took the microphone and began to read phrases from a book called "Necronomicon"...

Sources differ on what happened next.

The Miskatonic Acid Test consists of "found footage" of that infamous night; the
people, the atmosphere, the music... and the horror.
